Abstract

The Extensible Authentication Protocol (EAP) is a generic framework
supporting multiple types of authentication methods. In systems
where EAP is used for authentication, it is desirable to avoid
repeating the entire EAP exchange with another authenticator. This
document specifies extensions to EAP and the EAP keying hierarchy to
support an EAP method-independent protocol for efficient re-
authentication between the peer and an EAP re-authentication server
through any authenticator. The re-authentication server may be in
the home network or in the local network to which the peer is
connecting. [STANDARDS-TRACK]
